Spiral Freezing Systems
Deep freezing systems are the result of years of research aimed at offering the best method for processing packaged or bulk food products.
The food products are conveyed on a belt conveyor and deep frozen in a freezing room with insulated walls of varying thickness depending on the required operating temperature.
The flexibility offered, the possibility of the belt conveyor operating in very low temperatures and the freezing technology incorporated all provide the ideal solution for conveying diverse food products from bakery (bread, pizza, cakes) to fresh produce as meat or vegetables.
The evaporators installed in the insulated deep freezing room and the powerful fans ensure an excellent air flow promoting a correct heat exchange and perfect fast and effective blast chilling guaranteeing food quality and an easy and efficient system to operate.
This latest generation belt runs on tracks, requiring practically no lubrication. It is a new stainless steel cross-bar conveyor made with special links whose main technical features are illustrated below.
Special self-lubricating plastic elements are inserted on the links. They are shaped underneath to form the shoe that allows the belt to slide on the rails, whilst the upper part is shaped to hold the product in place.
A particular feature of the drive system is its special plastic wheels that, in addition to minimizing noise and friction, have a special engage/release system that makes maintenance/adjustments much simpler, allowing all such work to be performed extremely quickly.
Depending on the application, the belt is supplied either with a stainless steel mesh or a plastic mesh, suitable for operating temperatures anywhere between +120°C and -40°C. Since it does not have the central structure that drum-type spirals typically have, the system allows air to flow freely, thus optimizing the various heat treatments. This particular feature also makes cleaning that much easier.
